FILLING-LEVEL MEASUREMENT DEVICE AND METHOD FOR MEASURING THE FILLING LEVEL ACCORDING TO THE PROPAGATION TIME PRINCIPLE

摘要

Provide a kind of level gauging equipment (5) of material level of the filler (1) that is used for measuring vessel (3), and a kind of described level gauging equipment of use (5) is measured the method for material level.Level gauging equipment (5) can be when restarting reliable measurements material level independently immediately, it comprises: at least one antenna (11) is used to launch transmission signals (S) and receives echoed signal (E); Signal processor (13), it is used for obtaining the echo function from the echoed signal (E) that receives, and this echo function comprises echoed signal (E) amplitude (A) that depends on the travel-time; Storer (17) is used for the data storage that container is specific at table, and the row of this table are used for receiving respectively the echo function, thus the echo function in the row with corresponding to the sequential storage of the material level of each echo functional dependence; And analytic unit (19), its addressable table is to determine material level.
